There is a law in economics: the law of value is the basic economic law of commodity production and commodity exchange, that is, the value of commodities depends on socially necessary labor time, and commodities are exchanged with each other according to the principle of equal value. In a private ownership society, the law of value spontaneously regulates production, stimulates the improvement of production technology, and accelerates the differentiation of commodity producers. In a socialist society, since the socialist economy is a planned commodity economy based on public ownership, the socialist market economy must consciously base and apply the law of value to promote the development of the socialist economy. This law is particularly evident in the field of cell phone jammers.

Looking at past signal shielding projects, the part that best reflects the value is the real needs of customers. In other words, the real factor that determines the price is the needs of customers. For example, in a 50m*50m indoor area, the cost of building a nearby base station without a base station will be lower than that of a base station; the cost of an open indoor area without obstruction will be lower than the cost of an area with obstruction; the cost of 24-hour uninterrupted full-band shielding will be lower than the cost of an intermittent one. The price of partial frequency band shielding is lower; the price of rough test shielding (only center shielding) is lower than the price of precise shielding; etc.

In the signal blocker project, according to the customer's needs, the layout of the site and the strength of the radio signal, the shielding system is often built in the form of shielding host + antenna distribution. This is a reliable technology that is more professional and focuses on results in the field of shielding. Military The shielding method preferred by police government units and security agencies. Compared with a single device, the system is more reliable. Its price also changes with the size of the shielding area and the on-site environment.

In families, some parents are worried that their children will consider buying jammers if they are addicted to mobile phone networks. They often secretly purchase signal jammers worth hundreds or even thousands of dollars. These devices will directly interfere with the use of mobile phones in the neighborhood. The three major operators will conduct investigations after receiving complaints. If found, they may be subject to illegal penalties.

Therefore, the determining factor in the price of mobile phone signal jammers is user demand. If the shielding requirement is high, the price will be high, and if the shielding requirement is low, the price will also be reduced. However, the original intention of shielding is to achieve results without affecting third parties, so a relatively perfect shield will not be too cheap, due to the law of value.
